Connectionfailure: what this error means and how to fix it

It happens that when a user logs into a certain resource, the user suddenly receives a Connectionfailure error message. What is this failure, many can imagine immediately, simply translating its name from English to Russian. But here about ways of elimination of a mistake it is necessary to tell separately.

Connectionfailure: what does this failure mean

First, we use the usual translation. If you look at the name Connectionfailure, which means this description, it's easy to figure out if you break up the combination into two parts ("connection error" - literal translation). It turns out that this is a message about the most common communication failure or the impossibility of establishing it.

Of course, there can be a lot of reasons for causing such an error, and they do not always depend on the user's network settings, although this can play a role.

The most frequent reasons for occurrence and the most common situations

This is in brief about Connectionfailure. What this error means is a little understandable. But when it appears, all possible situations of its manifestation should be taken into account. Perhaps the problem is with only one particular resource, because it is carrying out technical work, and maybe the server itself, as they say, just "fell down." An eloquent example is the problem of 2014 with the site VK, when in general no one could go to him. By the way, this failure is typical for most social networks or resources with online games.

Also, the problem may be with the provider. If the input is not possible on all resources, the cause should be explicitly searched in the network or the settings of the browser used.

But if you look at local settings, among the things that can cause such a failure, there are several main reasons:

• Impact of viruses and malicious codes;
• Problems with the browser;
• Blocking connections by an antivirus or a firewall;
• DNS cache overflow and too many temporary files;
• Violation of the integrity of the Hosts file.

Connectionfailure error: what is this in terms of the ability to fix a failure

To resolve this issue, you should start by fully scanning the system for viruses. It is desirable to use some portable applications, and even better to boot from the Rescue Disk before the start of the system.

You can also try to enter the resource of interest to the user through another browser. Perhaps the reason is that the program used by default has too many extensions and add-ons, including the notorious AdBlock blocker. They can be disabled or deleted.

Perhaps the site is blocked by an antivirus or firewall. They should be temporarily disconnected and try to enter the site again. If the reason really is this, you will have to enter the site address in the list of exceptions (for the firewall you need to set a new rule).

To clean up temporary files, you can use optimizer programs that will delete content without user intervention, and to clear the DNS cache, you should call the command console with administrator-level privileges and use the ipconfig / flushdns command.

If you specify automatic receipt of addresses in the TCP / IP settings, which is the most common, for DNS you can specify the addresses of Google services, and then try to enter the resource again.

Finally, you can open the Hosts file and check its contents. If there are any addresses at the bottom (after the local address string, which starts with the value 127.0), they simply need to be deleted.

Instead of the total

Here, in principle, and all that relates to Connectionfailure failure. What does this error mean, it seems, is already clear to all users. Correction, as can be seen from all of the above, also presents no special difficulties. If the problem is not eliminated, in the extreme case, you can roll back the system to the state when everything worked. But in the case where the occurrence of a failure does not depend on the user, it is best to contact the provider to make a ping of the external signal coming from the computer or the user's router.
